Invention herewith described refers to the vacuum unit with chemical set for harmful and fire gases belongs to the field of equipment i.e. devices for protection against toxic or harmful substances, denoted by the international patent classification (MKP): A62B15/00.Into the chamber (5) of the chemical set for cooling and neutralization of harmful and toxic fire gases are introduced the fire products with present gases through the supply installation (1), (2) (3) and the fan (4) so that in this chamber (5) is realized the direct diffusion of gas mixtures with water which is supplied from a separate installation (25) of water and spray. Another method of work is based on the neutralization of harmful and toxic substances in fire gases as well as carbon monoxide with the appropriate reagents and water as solvent, which are introduced into this chamber (5) of the chemical set through special installations for these needs and purposes. Purified and cooled air returns to the same room, and the water used in the process is sent to open space or to the sewage.
